Abstract

The invention discloses a novel oil-water separation device for oil field water treatment, which comprises a separated water collecting cylinder; a cyclone centrifugal working cylinder is arranged inthe separated water collecting cylinder, and a cyclone assembly is arranged in the cyclone centrifugal working cylinder. A secondary separation conical barrel is further arranged between the upper endof the cyclone centrifugal working barrel and the inner side wall of the top of the separated water collecting barrel, the bottom surface of the separated water collecting barrel is further connectedwith a liquid inlet pipe communicated with the bottom of the cyclone centrifugal working barrel, and the top of the separated water collecting barrel is further connected with an oil outlet pipe communicated with the top of the secondary separation conical barrel; a water outlet is further formed in the bottom of the separated water collecting cylinder. According to the novel oil-water separationdevice for oil field water treatment, the problem that in the prior art, the oil removal effect is not ideal or the cost is high is solved.

Description

technical field [0001] The invention belongs to the technical field of oil removal devices, and relates to a novel oil-water separation device for oil field water treatment. Background technique [0002] After the oilfield development enters the middle and late stages, the water injection process becomes the main development mode, and the oil content in the injected water exceeds the standard, which will reduce the water injection efficiency. Therefore, taking necessary oil removal measures in the injection water treatment process is an important measure to ensure the effect of water injection development. At present, the commonly used measures for oilfield water treatment and oil removal include gravity separation method, gas flotation method, chemical oil removal technology and microbial oil removal technology. Although there are many methods, most of them have limitations. The gravity separation method has mature technology and low equipment requirements, but the degreas...
